Some time ago, I used to like looking for new and strange metal bands related to folk, epic, gothic music and other styles and I found one called Alestorm. I really liked the artwork in their covers and decided to find out who the illustrator was. It turned out to be a German artist called Ingo Römling.
What I like about his art is its cartoony feeling with a really nice harmony in colors as well as the stylized characters that look really cool. He also gives the illustrations a really nice texture that makes them feel very traditional.
